Inventor: OKAMOTO SATORU
IPC: H04N5/378
Filed: 1988-11-01
Abstract: PURPOSE:To effectively utilize a memory by retrieving the free area of a memory, and successively transmitting picture data in the next area. CONSTITUTION:At the time of photographing, an interface 15 is controlled by a system controller 42 so as to output the picture data to a connector 16 side, and the compressed picture data are stored into the picture data area A of a memory card 33. Next, when the controller 42 is selected for a paging operation, the controller 42 reads the picture information area B of the card 33, and retrieves the presence/absence of the free area of the area A. When the free area is retrieved, the picture data described in the next area are transferred to the free area where the controller 42 is erased. Thus, by successively transferring the picture data stored into the next area to the free area, the area A in a condition filled with the picture data is stored. Thus, the free area is practically expanded, and even when the size of the picture data is made variable, they can be recorded.

IPC: F04C18/107
Filed: 1988-10-31
Abstract: PURPOSE:To reduce thrust loss and slide motion loss and achieve a high efficiency in a helical blade type compressor by composing a cylinder and a piston symmetrical at a center part of their length, leading subject fluid to be compressed to the center part, and taking the fluid from both end parts. CONSTITUTION:For a compressor of a helical blade type having compression elements formed symmetrical at a center part, subject fluid to be compressed is led to the center part and taken out from both end parts. Thrust forces produced in operation chambers on the right and left side along the length of a cylinder 15 and a piston 16 act from both end parts to the center part, where the sizes are almost the same while the directions are opposite to each other, and they offset each other to reduce thrust loss. In addition, because the subject fluid is separated to the right and left, a pitch of spiral groove on the suction port side necessary for obtaining a predetermined elimination volume can be small. Deformation distortion produced at blades 21a, 21b is reduced greatly, thereby slide motion loss can be reduced.
